Cons: Didn't work at all. The USB plug is poor quality and not a standard size, you can push it in too far, and you can move it from side to side. Obviously, this makes for a very bad connection. Even tinkering with it, I couldn't get a solid connection to read a memory card. Very Disappointing.
Summary: at first my computer wouldn't reconize my card reader or my camera (it was a windows bios/port problem) after a fresh install of ol' XP it worked fine. if you have problem where windows doesnt reconized the drive as a removable storage, you have a driver issue with windows. IT IS NOT THE DRIVE.
Pros: work with my micro SD card. basically putting a card reader into this card reader. Works great!
Summary: Don't buy this device, buy a reputable brand. Other than that, newegg still had great prices and fast shipping.
Cons: The very first time I used this device it lost all the data on my SD card, which happened to be the better part of a GB of pictures. It doesn't matter how cheap this device is, don't chance losing your data.
Pros: Works fine! Very portable. Pop one cap off to reveal the USB, and the other end for the card. The caps can be put back on even with a card inserted. And you cant beat the Newegg price and fast shipping!
Summary: If you have an extra SD card laying around, this will effectively turn it into a USB flash drive. Or, just tuck this in your bag/briefcase for when you need to transfer some content from/to your handheld's SD card to/from a PC that doesn't have an SD reader already attached.
Pros: Smallish, lightweight, no drivers needed, compatible with FAT32 SD cards (up to 4GB)
